Review on Spigen Rugged Armor Apple Watch Case 40mm - Navy Blue: Designed for Series 6/SE/5/4 by James Turpin

Protects the watch well. Despite this, I swam with them several times - at first there were no problems. Then I did an EKG and everything was shaky. I decided there was water stuck between the case and the watch so I removed the case and dried it. I noticed that the metal (stainless steel) has tarnished in several places. Barely noticeable but I expect it to get worse as I continue to use it in the water.
